Guerra was extra sharp at the World Showcase, striking out 8 hitters in 3 innings of work and generally overmatching most hitters. It looks like Guerra has toned down his unique jump and throw delivery a bit, although he’s still unconventional, and this will help him in the future. Guerra threw 88-92 mph in Fort Myers, averaging 91 and his secondary pitches were very good, perhaps the best we’ve seen them. His curveball was 75-79 mph with sharp bite, while his change showed plus sinking action at 78-80 along with plus big league arm speed. Guerra is one of the better makeup players in the country in our book, combining a great on-field intensity with a loose and friendly personality off the field. He’s signed to go to Arizona if the draft doesn’t get him first. There's going to be a lot of mixed feelings among highest level scouts. Of course they're all going to like his arm, it's one of the best in the country. The question is, will he be better or worse if he has to change his delivery.

With the top fastball at the showcase, Guerra drew attention with his powerful hop-delivery and ease at which his arm worked. He dominated 3 impressive innings maintaining 90-93 mph velocity on the fastball and a hard 2-plane breaking ball at 78 mph. He also showed an 80 mph change-up and mixed all three pitches well. We have seen him up to 96 mph this year and in Waco he settled in consistently at 91-92 and filled the zone with strikes. His arm is one of the most gifted in the class.

Guerra's unique delivery can best be described as controversial, but there was no questioning he had the quickest and loosest arm in Lincoln. He was consistently 90-91 mph and we’ve seen him as high as 96 mph in the past. Guerra compliments his heat with a 77-78 curveball that has occasional sharp biting action, a smaller 83 mph slider and a 80 mph change up that had good deception for someone with that much arm speed. But the delivery has more than a couple of scouts and coaches questioning whether it is legal per baseball rules or not. At least one coach has sent in film to the NCAA for a ruling before he decides to start recruiting Guerra. What Guerra does is comparable to what a women’s softball pitcher does prior to release, except with a standard ¾’s release point. Guerra takes a hard, big hop off his back (right) leg at the point when he starts coming forward in his delivery, lands hard on his front (left) leg and completes his arm stroke with his right leg probably a foot in front of the pitching rubber. While every pitcher looses contact with the rubber before he throws the ball, Guerra’s action is so severe and exaggerated that there is little, if any, precedent for it at this level. What his delivery tends to distract from, however, is just what a loose, quick arm Guerra has. He might be a big question mark for a pitching coach, but there is no questioning the quality of his arm. Javi has one of the very best arms in America.

Big time 04 arm! 88 to 90 mph fastball with life. Very fast arm works well. Tight breaking ball is promising. Also showed outstanding hitting ability. Good contact swing, line drive hitter with power. Body projects, he could be a top national prospect in 04. The real deal!
